6 Claims. '(Cl.- 15-134) This invention relates to an improved liquid dispensing can, one particular use for which is the dispensing of liquid cleaning materiaLwhich is provided with a wiping or cleaning padfed 5 with liquid from the can.

An object is to provide a can container'of this type which is simple, inexpensive, and readily adaptable for use and wherein the liquid is protected from evaporation. The container structure is vsuch that the liquid may be dispensed for use through the pad without manual adjustment or manipulation of operating parts but merely by tipping over the can to the position of use.

A further object is lto provide a can of this character so constructed that the flow of liquid to the pad would be facilitated and yet such iiow is so restricted that the pad will not be unduly saturatedwith liquid.

A meritorious characteristic is the provision of an article of the class described which possesses an attractive appearance and wherein the Y operating parts arel all protected from exposure and which is adaptable to a can of conventional construction. Y

More specifically, the invention resides in anr improved cap adapted for engagement with the threaded neck of a tin can of conventional construction, which cap has a cleaning pad portion of substantially greater diameter than the neck, which cap vis provided with valve mechanism which controls the flow of liquid from the can tothe pad and it is also provided with a portion engageable with the neck of the can to secure 35 the cap to'the'can. The cap surmounts the'rtop of the can forming an attractive enclosed dome thereover. The cap is provided with a valve controlled well or compartment of limited lcapacity which immediately superimposes the neck of the can and' is separated from theremaining interior of the cap and which feeds the cleaning pad. l

Other objects, advantages, and meritorious features of the improved ystructure will more fully appear from the following specication, appended claims, and accompanying drawing, wherein:

Figure l is an elevation of the can embodying the invention,

Fig. 2y is an enlarged cross-sectional view through the top of the can and cap,

Fig. 3 is ran elevation partly broken away of a cover for the cap, land Fig. 4 is a view showing a portion of the can and the separate `elements that go to make up the canarranged in spaced superimpositionas they would ybeassembled together.

It has heretofore been proposed to provide containers of lone type or another with a closure cap fitted with a wiping pad so that cleaning 5 iiuid might be fed to the pad and the pad mightl be available for use as a means for removing spots from clothing or the like. These containers were either of the bottle or can type. The purpose of this improved structure is to providev l a cap which is receivable'upon a can of conventional construction, Which can has a threaded neck of substantially less diameter than the body of the can and which cap is fitted with a wiping pad of substantially greater diameter than the l neck of the can and which cap is vconstructed to close completely over the top of the can and is fitted with valve control means.

Iny the drawing the can is indicated as I0. The side wall supports a crowned top which carries an upstanding threaded neck of reduced diameter as compared with the top and the can is provided with a marginal bead rising above the adjacent portion of the top.

The improved cap of this invention is assembled from a plurality of parts and comprises a crown portion I4 apertured as at I6 and provided Witha skirt I8 having an outwardly turned flange 20. A porous cleaning pad 22 is provided. This may be formed of cloth having a pile, such as shown, so as to form a good wiping and cleaning surface. A- piece of felt 24 may also be provided to rest directly over the perforations I6 in the crown I4 underneath the wiping cloth 22. This wiping cloth is secured stretched over the crown I4 by retainer skirt or ring 26 which has a flange 28 that grips the margin of the clothv on the fiange 2li of the skirt I8 as shown in Fig. 2.

The cap is provided with a closure element or socket member which has a closure wall 30 that o covers the opening in the neck I2 of the can. This element 30 has a skirt portion 32 that engages the threaded neck of the can to secure the cap to the can. There is an angular ring 34 that is secured to thev skirt ring 26 and which 45 also is secured to the skirt of the closure 32 as shown in Fig. 2 so as to support the socket element within the cap as shown in such figure of the drawing. This securement may be obtained by soldering, welding, or in any suitable manner.

The closure wall 30 is depressed and apertured as at 36 and a small check valve 38 seats in the depression and closes the aperture controlling the flow of liquid therethrough, all as shown in Fig. 2 of the drawing. There is a sealer ring or 55 gasket` l0 which is arranged between the closure wall $0 within the crown and spaces the crown above the closure wall 30 providing a smalLcompartment or well within which the ball check 38 is positioned for movement.

Received within the socket member is a second sealer ring or gasket I2 that superimposes the neck of the can and forms a tight seal between the closure element and such neck as the parts are screwed tightly together.

In the view of Fig. 2 there is shown a removable cover element 44 which is received over the cap as illustrated in dotted outline. This is to protect the wiping pad and the wall of this cover element has a flaring skirt portion which overhangs the top of the can and would seat close thereover. In this view of Fig. 2 there is also shown a sealing disc 46 which is received within the socket underneath the gasket I2 and which closes the aperture through said gasket in said closure 30 and which is in place while the can is in storage or prior to its reaching the ultimate user, so as to prevent any such evaporation of cleaning fluid. This cleaning iiuid is ordinarilyv quite volatile and evaporation may occur even notwithstanding the valve control, This sealing disc will be removed and put aside by the user.

To use the can for cleaning, the cover 44 is removed and the cap is unscrewed and the sealing disc 46 removed. The cap is then screwed back in place and it seats snugly against the top of the can so as to form a continuous protective dome thereover. Upon .inverting the can suiilcient fluid will pass out through the valve controlled opening in the closure into the space between the closure and the crown and will pass through the perforations in the crown and through the 4porous felt 24 and wiping pad 22 to moisten the upper surface of the pad so that it may be used as a cleaning pad to remove spots in the ordinary manner.

The ball check 38 will prevent any excessive evaporation of cleaning fluid when the can is not in use and it also serves because of its permitted play between the crown and the closure cap to facilitate the outflow of liquid. The liquid flows out more readily than it does if -the ball is not in place. 'I'his may be due to a slight capillary action. The liquid is preventedby the gasket 30 from flowing out from the space between the neck and the skirt of the cap and leaking down over the outer wall of the can. Any liquid that is left unused after the use of the can and which does not flow back into the can through the valve control opening is retained within the compartment between the crown and the closure cap and cannot escape outwardly over the top of the can.
